Description
Technical field：
The utility model is related to a kind of sealing devices, more particularly to one kind being applied to damper shaft sealing device for hot-blast damper.
Background technology：
The air door shaft end that coal pulverizer hot wind adjusting door all occurs in majority thermal power plant at present takes packing to compress sealing, should
Sealing means are axial linear sealing, are had the following problems：1, packing tension easily leads to bite in valve event；2, packing pine excessively is easy
Cause poorly sealed, First air is caused to leak outside；3, long-term operation packing and axis relative motion, cause packing wear out failure；4、
It causes door-hinge can be caused to damage when packing wear out failure is serious with longtime running when packing is excessively loose, can not repair, and then aggravate mill
Damage causes vicious circle.Bite, poorly sealed, door-hinge damage occurs since the presence of problem makes hot wind adjust door, to maintenance people
Member's line service amount brings immense pressure, increases workload, is unfavorable for the raising of production efficiency；In addition poorly sealed to make
There is serious pollution in environment, does not meet environmental requirement.
Utility model content：
To solve the above problems, being applied to hot wind the purpose of this utility model is to provide one kind adjusting door door-hinge sealing dress
It sets.
The purpose of this utility model is implemented by following technical solution, and one kind being applied to damper shaft sealing device for hot-blast damper,
It includes door body and the door-hinge through the door body, be arranged with successively on the door-hinge on the outside of the door body static seal plate,
Dynamic sealing plate, bearing and end cap, the static seal plate are sealedly and fixedly connected with the door body, the dynamic sealing plate and the bearing
It is fixedly connected with the door-hinge, the static seal plate and the dynamic sealing plate fit closely, and the end cap is solid with the door body
Fixed connection.
Further, the end cap is equipped with screw hole, and fastening corresponding with the screw hole is fixed in the door body
Nut, be arranged in the screw hole bolt, the door body and the end cap be spirally connected by the bolt and the fastening nut it is solid
It is fixed.
Further, the dynamic sealing plate connect or is keyed with the door-hinge interference.
Further, the bearing connect or is keyed with the door-hinge interference.
The advantages of the utility model：The utility model on the outside of the door body that hot wind adjusts door by being fixedly installed static seal
Plate is arranged dynamic sealing plate on door-hinge and bearing, static seal plate, dynamic sealing plate and bearing is fastened by end cap, realizes circumferential
Face seals, and effectively prevents air leakage phenomena caused by existing axial linear sealing device is poorly sealed and frequent wear and environment is dirty
Dye.
Description of the drawings：
Fig. 1 is traditional damper shaft sealing device for hot-blast damper；
Fig. 2, which is that embodiment 1 is a kind of, being applied to damper shaft sealing device for hot-blast damper structural schematic diagram.
In figure：Door body 1, door-hinge 2, static seal plate 3, dynamic sealing plate 4, bearing 5, end cap 6, fastening nut 7, bolt 8, key 9,
Packing 10.
Specific implementation mode：
Embodiment 1：
One kind being applied to damper shaft sealing device for hot-blast damper comprising door body 1 and the door-hinge 2 through door body 1, in door body
Static seal plate 3, dynamic sealing plate 4, bearing 5 and end cap 6 are arranged on the door-hinge 2 in 1 outside successively, static seal plate 3 is sealed with door body 1
It is fixedly connected, dynamic sealing plate 4 and bearing 5 are fixedly connected with door-hinge 2, and static seal plate 3 and dynamic sealing plate 4 fit closely, end cap 6
It is equipped with screw hole, fastening nut 7 corresponding with screw hole is fixed in door body 1, bolt 8, door body 1 and end are arranged in screw hole
Lid 6 is fixed by bolt 8 and fastening nut 7 by being spirally connected.
As a kind of specific implementation mode, dynamic sealing plate 4 and bearing 5 are connect with door-hinge 2 by key 9.
The above is only the preferred embodiments of the present utility model only, is not intended to limit the utility model, all in this practicality
Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the guarantor of the utility model
Within the scope of shield.
